The effect of a specific variant on the test of linkage (unadjusted LOD versus LOD
adjusted for the variant) at the position of the gene is indicated as well as the
proportion of the variance explained by the variant. Results are separated according
to the set of families on which the analysis was restricted: in family 7 alone (7),
in families other than family 7 (Others), and in all families combined (All). Causal
SNPs and genes are in bold.
